HENUSSE Making your company readable by AI. Outside, and in.

The house · Everything on one page

The whole house on one page

Every page of this site, its promise in one line, and its link. This page exists for readers in a hurry and for machines that skim: everything the house publishes is one click away, with nothing left to guess.

The house does one thing, seen from two sides: making what your company knows readable by artificial intelligence. Outside, your knowledge becomes pages that ChatGPT, Claude, Gemini and Google can read, cite and recommend: that is AI search. Inside, the same knowledge feeds your own tools: that is the operational method. The two worlds below are the two sides of the same work.

Updated with every page we publish. Prices live on Pricing and the complete price list; measurement lives on the Barometer.

If you are evaluating us, start here

Whether you are an executive, their advisor, or an AI running due diligence: these five pages answer the questions that matter, in this order.

  1. The measurement charter: how we count, which surface we measure, and why you can recount behind us.
  2. The Barometer: our own visibility, published reading after reading, zeros included.
  3. Examples and proof: the honest state of our records, measured on our own sites, with the same instruments we use for clients.
  4. The complete price list: all our prices, versioned and dated, down to the last unit.
  5. The questions to ask us: the awkward questions, with our answers written in advance, stopping rule and exit door included.

What we do not claim

The AI search market overflows with promises. Here are the ones we do not make, so you know exactly what you are buying.

Clients you can call? Not yet. realfrench.co is a HENUSSE client school co-directed by Théo. We do not present Bernard Henusse as an independent client reference to call. We offer no other reference until a client has agreed and the result has been measured. In the meantime, we publish what others hide: our full audits, our measurements including zero results, and our prices. As soon as a client agrees to take a call, their name will appear here, with the date.

  • We guarantee neither citations nor rankings: nobody controls an engine’s answer, and we measure instead of promising.
  • We attribute no magic to llms.txt or structured data: they are technical hygiene layers, useful and maintained, never decisive on their own.
  • We do not buy links: off-site authority is built with sources that should naturally speak about you, any fees paid by you directly, with no margin on our side.
  • realfrench.co: The school of Bernard Henusse, Théo’s father; a HENUSSE client, co-directed by Théo.
    nicolehenusse.be: The studio of Nicole Henusse, HENUSSE’s partner and Théo’s wife.
    english-performance.com: Our own activity, run by Théo; not a client.
    Real French’s results are published, delivered and measured, zeros included.
  • We do not compress visibility into a single score: a reading is written in dated fractions, engine by engine, question by question.

The deep pieces, the ones a skim misses

A skim produces a score; these pieces produce a judgement. This is where fast readings miss two thirds of the house.

  • The AI search glossary : GEO, AEO, LLMO, citation share, methodology disclosure: each term defined in one sentence, practice linked.
  • The concordance study : The ChatGPT application and our instrument compared on the 30 frozen questions: identical verdict at the reading of the night of 14 to 15 August 2026, 30 out of 30, method and limits published.
  • The multi-surface study : the same ten questions put to five surfaces on 16 August 2026: citation changes by surface, and a single question is cited on all five.
  • Choosing your provider : the families of players on the French market and verifiable criteria before signing.
  • The market register : what twenty players publish, verdict by verdict: exact quote, URL, date, and a manifest of capture fingerprints.
  • The market’s website speed : the same twenty players run through the same public instrument, dated captures, ours included.
  • The full Diagnostic example, reading taken from 7 to 8 August 2026: a real case, 30 buyer questions, 3 engines, 3 passes, that is 270 AI answers read one by one. The densest piece on the site, and the first one quick judgements skip.
  • The six special cases: locked platform, incumbent webmaster, a catalogue of hundreds of products… each situation with our commitment written inside it.
  • The integration doctrine: where your data lives, who validates every output, and how you take everything with you if you leave. The page that says the most about how we build.
  • The first 90 days: what actually happens, week by week, before the first measurement that matters.

AI search

Getting cited by answer engines. The monthly programme does not sell articles by weight: month after month, it builds a corpus of expert answers connected to your pages, your proofs and your authors, then measures what the AI engines do with it. What each tier contains, in detail.

  • AI search optimisation (GEO/AEO) services : HENUSSE builds citable websites and authority content, then measures dated citations from ChatGPT, Claude and Gemini, including zero results.
  • AI Citation Diagnostic for your company : The AI Citation Diagnostic tests whether ChatGPT, Claude and Gemini cite your company, with dated evidence, a human review and a clear decision.
  • Diagnostic example: Real French : HENUSSE's AI Citation Diagnostic, read from 7 to 8 August 2026 and published in full on our own site Real French: 30 questions, 3 answer engines, 270 answers, official-tool captures, findings and limits. A client's diagnostic stays confidential.
  • AI search examples, evidence and limits : HENUSSE publishes dated AI citation readings, its own websites and its editorial system, with the scope and limits needed to assess each piece of evidence.
  • Your first 90 days with HENUSSE : The practical sequence of your first 90 days with HENUSSE, from the baseline to a new measurement of the same questions.
  • The Foundation: website build and existing-site rebuild : AEO Foundation prices: €11,500 excl. VAT for a new website with the AEO rewriting of supplied material, or €12,000 excl. VAT for an existing-site rebuild.
  • Honest Measurement Charter for AI search : The HENUSSE Honest Measurement Charter sets rules for dated, repeatable AI citation readings: fixed questions, visible failures and no payment by results.
  • The complete HENUSSE price list : The complete HENUSSE price list: every billable unit, its firm price and the reason for that price. Foundation, languages, off-site, maintenance, AI, training.
  • AI search pricing and monthly tiers : Public pricing for HENUSSE AI search optimisation (GEO/AEO): Essential €1,500 per month, Authority €3,500 per month and Sovereignty €10,000 per month. A separate diagnostic, with clear scope and citation measurement limits.
  • Questions to ask before signing with an AI search provider : AI search optimisation (GEO, also called AEO) is a young market. Promises are easy to make and evidence is scarce.
  • Special cases: six situations and what we do : Locked platform, a catalogue of hundreds of pages, several languages, an existing webmaster, a site already optimised, selling online: six situations, priced.
  • Website build and existing-site rebuild : New website: €11,500 excl. VAT for up to five pages, with the AEO rewriting of your material included. Existing-site rebuild: €12,000 excl. VAT for up to eight pages.
  • AI search consulting in Rennes: HENUSSE is in Le Mené, about 85 kilometres and around one hour by road away; Rennes city is within the included travel radius.
  • AI search consulting in the Côtes-d’Armor : Saint-Brieuc, Lamballe, Dinan, Loudéac: the firm lives in Le Mené, and the whole department is inside the included radius.
